Newcastle Jets goalkeeper Mark Birighitti is hopeful of a move to Bayer Leverkusen.

"I left a good impression over there [at Leverkusen]. They were quite happy with me, with the way I went," Birighitti said, per Iain Strachan at Goal.com. "It's still up in the air at the moment. I'm just playing a waiting game now."

Birighitti is a fantastic shot-stopper and one of Australia's best young talents, so it is not a surprise that Leverkusen are interested in him.

The problem with this move is that Birighitti will not be given leeway to beat out Bernd Leno, one of the best goalkeepers in Germany.

Leno would need to have a Joe Hart-like fall for an extended period of time before an opening emerges for Birighitti.

He could end up like Borussia Dortmund's Mitchell Langerak, who has sat on the bench for the better part of four seasons.

Spartak Moscow centre-forward Yura Movsisyan is being targeted by Premier League teams.

"Sky Sports understands a number of Premier League clubs are tracking Spartak Moscow forward Yura Movsisyan," per Pete O'Rourke at Sky Sports. The broadcaster reports that the 26-year-old is "one of the hottest properties in Europe."

Movsisyan scored 16 goals from 63 shots in 27 league games for Spartak in 2013-14.

16. Jonathan Williams

"I spoke to my agent who says [Swansea] were interested [in signing me]," Williams said, per Simon Gaskell at Wales Online. "I need to play football, preferably at Palace, but if not I'd have to consider playing elsewhere."

Williams has superlative technique and is nicknamed Joniesta after Barcelona's FIFA World Cup-winning midfielder Andres Iniesta.

However, injuries and lack of playing time has hindered Williams from fulfilling his potential.

8. Youssouf Mulumbu

"Youssouf completed a good, consistent season despite the difficulties West Brom encountered," Pingisi said, per Bill Howell at the Birmingham Mail. "He's now aspiring to test himself in European competitions."

Mulumbu is a perfect mid-tier footballer, but whether or not he can take the next step up is debatable.

3. Thomas Mueller

Bayern Munich forward Thomas Mueller wants to hold a frank discussion with club management over his future.

"I am not the type of guy that says 'alright, I have played a good part and will keep my mouth shut and everyone else is able to do with me whatever he wants,'" Mueller said, per Stern (h/t Jamie Jackson at the Guardian).

He continued: "It's no secret that Louis van Gaal and I have a relationship that goes a little beyond the normal relationship between coaches and players."

Translation: Mueller is not content with being shifted all over the field under Pep Guardiola and would be open to moving to Manchester United to play under Van Gaal.

Mueller has played on the right, started centrally, appeared on the left and up front.

Perhaps he wants to play in one position, where he can then have a world-class season, rather than an elite season while constantly changing positions.

2. David Villa

New York City centre-forward David Villa is set to play 10 A-League games for Melbourne City as part of a loan deal between the sister clubs, per the Australian.

"I'm sure that playing for Melbourne City FC will be a marvellous experience," Villa said, per Football Australia's official website. "It will be ideal for me to get some competitive football in the period before the MLS [Major League Soccer] season gets under way."

Villa scored 13 goals in La Liga for Atletico Madrid last season and would have netted more if not for teammate Diego Costa.

His loan transfer is a big coup for Australian football.

Melbourne City were previously known as the Melbourne Heart, but were rebranded to align with their parent club, Manchester City, per Matt Windley at the Herald Sun.

Both New York City and Melbourne City are a part of Manchester City's footballing portfolio.
